 Introduction

The La Dade-Kotopon Municipal Assembly used to be a Sub-Metropolitan Assembly under the Accra Metropolitan Assembly until June 2012 when it attained a Municipal status. Like all other Municipalities, the La Dade-Kotopon Municipal Assembly was established by Local Government Act, 1993 (Act 462) with Legislative Instrument 2133.

 This was in line with Government’s objective of deepening decentralization and grassroots development by reducing the size of larger Metropolitan, Municipal and District Assemblies into manageable sizes.

The Municipality covers an area of 36.033 square kilometres. It is bounded on both North and West by the Accra Metropolis, on the East by the Ledzokuku Krowor Municipality and on the South by the Gulf of Guinea (see map below).

Physical Features

Geology and soils

The coastline of La Dade-Kotopon has a series of resistant rock outcrops, platforms and sandy beaches near the mouth of the Kpeshie lagoon. The coastline is exposed and because of the close proximity of the continental shelf and strong coastal wind action, it is subject to severe erosion. The lagoon systems, which are relatively small and flushing, have been impeded by siltation or the construction of embankments, which have restricted tidal flow.

The soils in the area can be divided into four main groups: drift materials resulting from deposits by windblown erosion; alluvial and marine muted clays of comparatively recent origin derived from underlying shale; residual clay and gravel derived from weathered quartzite, gneiss and schist rocks, and lateritic sandy clay soils derived from weathered Accraian sandstone bedrock formations.

Climate

The La Dade-Kotopon lies in the Coastal Savannah zone. It has two rainy seasons. The first begins in May and ends in mid-July while the second season begins in mid-August and ends in October. The average annual rainfall is about 730mm, which falls primarily during the two rainy seasons. There are few occasions where the Municipality experiences showers and thunderstorms in November and December. Rain usually falls in intensive short storms and gives rise to local flooding where drainage channels are obstructed.

There is very little variation in temperature throughout the year. The mean monthly temperature ranges from 24.7°C in August (the coolest) to 28°C in March (the hottest) with annual average of 26.8°C (Dickson and Benneh, 2001). As the area is close to the equator, the daylight hours are practically uniform throughout the year. Relative humidity is generally high varying from 65percentin the mid-afternoon to 95percentat night. The predominant wind direction in the Municipality is from the West South West (WSW) to the North North East (NNE).

Vegetation

The vegetation of the Municipality consists of dense clusters of small trees, shrubs and grasses, which grow to an average height of six metres. The grasses are a mixture of species found in the undergrowth of forests. They are short and rarely grow beyond one metre. Ground herbs are found on the edge of the shrub. They include species, which normally flourish after fire.

Mangroves, comprising of two dominant species, are found in the tidal zone of all estuaries sand lagoons. Salt tolerant grass species cover substantial low-lying areas surrounding the lagoons. These grasslands have an important primary production role in providing nutrients for prawns and juvenile fish in the lagoon systems.

The soils are mostly infertile for the cultivation of crops. However, there are pockets of small-scale agricultural activities where farmers mostly grow vegetables and fruits for both consumption and commercial purposes. There is however, competition for the limited agricultural land in the Municipality owing to the construction of houses, roads and other developments.
